OIL-BURNER.

Specification of Letters Patent.

Patented Mar. 26, 1918..

Application filed November 21, 1917. Seria1No.203,2 27.

To all whom it may comm:

Be it known tiat'l, Connnnmus WV. RussnLL, a citizen of the United States, residing at Burlington, in the county of Des Moines and State of Iowa, have invented a new and useful Gil-Burner, of whichthe following is a specification.

This invention relates to oil and gas burners particularly designed for use in connection with heating furnaces, one of the objects of the invention being to provide means whereby an extensive gas flame can be produced extending over a considerable area, the flame being so located as to be especially useful in heating the fire pot of a hot air furnace, or a hot water or steam furnace or similar structure.

A still further object is to provide means whereby the size of the flame can be readily controlled, the burner consisting of a series of vaporizing chambers which can be placed successively into operation thus to increase the size of the flame and the heating capacity of the furnace at will.

' A further object is to provide a burner which can be manufactured cheaply, can be easily installed, and whichby supplying air to the flame requires the minimum amount of oil fuel.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the in vention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings Figure 1 is a central vertical section through a burner embodying the present improvements.

Fig. 2 is a section on line 2-2 of Fig. 1.

Referrin to the figures by characters of reference designates a portion of the grate of a furnace and mounted on this grate is a tubular core 1 the lower end of which is screw-threaded and engaged by a cap 2 constituting the base of the burner. Another cap 3 is screwed onto the upper end of the core and serves to close said end.

The core is provided with external screwthreads at intervals as shown at d and mounted on the core are superposed pairs of concavo-convex dlsks, each pair including a lower large disk 5 and an upper smaller 1 disk 6. The lower disk constitutes a fuel container while the upper disk is oppositely disposed and constitutes a hood, the periph eral portions of the two disks being slightly separated, thus to form an unbroken or continuous annular slit or opening 7 serving as a vent for the generated gas. Each of the disks has as internally screw-threaded hub 8 and these hubs engage the adjacent threaded portions l on the core 1. Obviously the disks, by being independently rotated, can be adjusted toward or from each other, thus toregulate the size of the slit 7 between them.

Extending into the core 1 from the bottom thereof are fuel supply pipes 9 and these pipes open into the spaces between the disks ofthe respective pairs, each pipe being pro vided with a controlling valve 10. In the present instance four pairs of disks have been illustrated and, consequently, four fuel supply pipes have been provided, each pipe having a valve 10.

Opening into the bottom of the core 1 is an air supply pipe 11 having a valve 12. Air outlet ports 13 are formed in the core close to each of the upper disks 6, these .out let openings being adapted to direct air into the flame of the burning oil directly under said disks, thereby to produce an intense heat.

It is to be understood that when a burner such as described is in position within a furnace, the peripheral portions of the disks 5 and 6 will be supported close to the wall of the fire pot. lVhen it is desired to use the burner fuel is first admitted through one of the pipes 9 into the lowermost disk 5. This fuel is ignited and the air and gas forms a gas flame which flows through the annular slit or opening 7 and the heat generated will result in the vaporization of all fuel contained upon the lowermost disk 5 and will also result in heating all of the disks above the fuel. as well as in heating the wall of the fire pot. Thus ultimately the gas generated between the lowermost pair of disks 5 and 6 will mingle with air supplied thereto through the lowermost openings or ports 13, thereby forming a highly combustible gas, which will burn with an intense heat at the outlet 7. When it is desired to increase the heating capacity of the burner additional fuel is directed into the disk 5 next-above the pair of disks in which gas is being gen-- eratedand as this disk 5 has been heated to a high temperature, the fuel will be vaporized promptly and Will mix with air and discharge as a gas at the annular opening 7 Where it will be ignited and thus add to the size of the flame. The flame can be further increased in size by directing fuel into the next highest disk 5 or into all of the disks, gas being generated at each of these points and becoming ignited at the annular openings 7 ()il at no time flows from the pairs of disks mounted on the core, the disks of each pair beingv oppositely disposed and spaced apart to form an annular slit, there being ports in the core for directing air from the core into the spaces between the disks of the respective pairs, and means for directing oil in controlled quantities into the spaces between the disks of the respective pairs.

2. A burner including a tubular core, superposed pairs of disks upon the core, the

disks of each pair being oppositely disposed and spaced at their peripheries to form a copies of this patent may be obtained for five cents each, by addressing 1;

gas outlet, said disks being adjustably mounted upon the core and relative to each other, and means for supplying oil incontrolled quantities to the spaces between' the disks ofthe respective pairs. 7

A burner including a tubular core, superposed pairs of disks upon-the core, the disks ofeach pair being oppositely disposed V I and spaced at their peripheries to form a gas outlet, said disks being adjustably mounted upon the core and'relative to each other, and means for supplying oil in controlled quantities to the spacesi'between the disks of the respective pairsthere being means for directing air from the core and 5 into said spaces to 1111K with generated gas. 7

4. An oil burner including a tubularcore having a valved air inlet, superposed pairs 7 of disks mounted on thecore, the disks of each pairbeing 4 oppositely disposed and spaced apart at their peripheries to'form gas outlets, there being ports for directing air from the core and intothe spaces between the disks of the respective pairs, and:

' means for directing oil into said spaces between the disks, said means including controlling yalves. j p
